The DECS-200-2L excitation regulator is used to regulate the excitation current of synchronous engines

DECS-200-2L excitation regulator is an important part of excitation control system, which is mainly used to regulate the excitation current of synchronous engine. It has the important performance of keeping the generator voltage stable, realizing the rational distribution of reactive power and keeping the power system stable. The development trend of excitation regulator is continuous digitization, integration and intelligence, which can realize fast information processing and control, and adapt to the development needs of modern power system.

The main functions of the DECS-200-2L excitation regulator include:

Maintain generator voltage stability: By adjusting the excitation current, the generator voltage is kept within the set range to ensure the stable operation of the power system.

Reasonable distribution of reactive power: Adjust the excitation current according to system requirements, so that each unit can share reactive power reasonably, and ensure the stability and economy of the power system.

Control system stability: Through the regulation of the excitation regulator, the frequency, damping and other parameters of the system can be controlled to ensure the stability of the power system.

Protection function: DECS-200-2L excitation regulator also has protection functions, such as over-current protection, over-voltage protection, etc., to ensure the safe operation of the unit and the power system.

The control mode of excitation regulator mainly has two kinds: voltage setting and current setting, which are used for constant terminal voltage regulation and constant excitation current regulation respectively. With the development of computer technology and modern control theory, the excitation regulator has gradually realized intelligence, and can make self-adjustment according to the operating state of the system to ensure that the system is in the optimal state.

At present, the main excitation regulator brands on the market include Danchuang Electric, National Xuzhen, Guodian Xuzhen, etc., and their prices vary according to different models and specifications.
